How To Install 7-Way Trailer Connector On 2015 Jeep Wrangler Unlimited  

Updated 09/07/2021 | Published 09/06/2021

Question:

I read this in a post and brought this based on your guys recommendations. This doesnt seem to work to change the 4 to 7 plug as suggested. I see no connector where it says. Thank you for your help. Expert Reply: I have exactly what you will need for your 2015 Jeep Wrangler Unlimited to tow your Vintage Airstream with brakes. The first thing you will want is a 7-way trailer connector at the rear of the vehicle and for this I recommend the Hopkins Endurance Quick-Install 7-Way Trailer Connector part # HM42190 which is a direct plug and play option that will not require you to cut or splice any wires/circuits. The square plug on the end of this connector will plug into and replace the 4-way trailer connector you have which is found near the drivers side taillight housing.

There are a few different trailer wiring harness options for a 2015 Jeep Wrangler Unlimited. The Hopkins Endurance Quick-Install 7-Way Trailer Connector part # HM42190 is only for models with the factory tow package. If you don't have the factory tow package then there won't be a square plug for the above and instead you'll need to start with a 4-way and adapt this to a 7-way. I recommend using the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C55124 and Universal 4 to 7-Way Adapter Kit part # ETBC7.

If the trailer has brakes then you'll also need a brake controller for which I recommend the Tekonsha BRAKE-EVN part # TK63VR.
